摘要:
The present invention relates to asparaginase variants. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants. The invention further relates to a process of producing a fermentation product, comprising: liquefying a starch-containing material to dextrins with an alpha-amylase in the presence of an asparaginase of the invention; saccharifying the dextrins to a sugar with a glucoamylase; and fermenting the sugar using a fermenting organism.
